To investigate the effect of being forewarned that they would be asked to identify repeated images on radiologists' recognition of previously interpreted versus new chest radiographs.
Thirteen radiologists viewed 60 posterior-anterior chest radiographs, 31 with and 29 without nodules, in two sets of 40 images each. Eight radiologists were forewarned and five radiologists were not forewarned of the memory task. Twenty images in each of the two sets were unique to each set and 20 images occurred in both sets. The readers indicated the presence or absence of any nodules during both readings, and in the second reading session they also indicated whether they thought each image had also occurred in the first reading.
There was no significant difference in recognition memory performance between forewarned and not-forewarned readers. Overall accuracy in distinguishing previously-viewed from new images was 60.7%.
Being forewarned of the memory task did not improve recognition memory.
研究预先告知放射科医师他们将被要求识别重复图像，对其识别先前解读过的与新的胸部 X 线片的影响。
13 位放射科医师观看了 60 张前后位胸部 X 线片，其中 31 张有结节，29 张无结节，分为两组，每组 40 张。8 位放射科医师被预先告知，5 位未被预先告知记忆任务。两组各有 20 张图像是每组特有的，20 张图像出现在两组中。读者在两次阅读过程中均指出是否存在任何结节，并在第二次阅读过程中还指出他们是否认为每张图像也出现在第一次阅读中。
预先告知和未预先告知的读者在识别记忆表现上没有显著差异。区分先前查看和新图像的总体准确性为 60.7%。
预先告知记忆任务并没有提高识别记忆。
